BUILDING.

SPECIFICATION forming part of Letters Patent No. 656,951, dated August28, 1900.

Application filed April 13, 1900. Serial No. 12,756. (No model.)

Fa-all whom it may concern:

Be it known that I, CHARLES F. W. DoEHR- ING, a citizen of the UnitedStates, residing in Philadelphia,Pennsylvania, haveinvented certainImprovementsin Buildings, of which the following is a specification.

The object of my invention is to so construct the partitions, floors,ceilings, and roof of a building as to materially lighten the weight andcheapen the cost of the same, these parts being at the same timerendered fire and water proof. These objects I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in which- Figure 1 is a sectional View of a building constructed inaccordance with my invention, showing the two upper floors, attic story,and roof of the same so far as the walls and framework are concerned,the coverings of the partitions and ceilings being omitted. Fig. 2 is aside elevation, on an enlarged scale, of a part of one of the partitionstructures. Fig. 3 is a longitudinal section of the floor and ceilingwith portions of the partition structure above and below the same, saidpartition structure and the ceiling having the coatings applied thereto.Fig. 4 is a transverse section on the line a a, Fig. 2. Fig. 5 is atransverse section on the line b b, Fig. 3. Fig. 6 is an enlargedsectional plan View on the line d cl, Fig. 3. Fig. 7 is an enlargedtransverse section on the lineff, Fig. 3. Fig. 8 is a vertical sectionillustrating certain modifications or special features of the invention;and Fig. 9 is an enlarged section on the line 2' 1', Fig. 8.

In Fig. 1 opposite side walls are represented at 1 1, the space withinthese walls being divided into rooms or apartments by means oftransverse partitions 2 and floor structures 3, the walls alsosupporting the roof-beams l.

The roof consists of strips 5, placed closely together edge to edge andnailed or otherwise secured to the roof-beams 4, so as to form acomplete sheathing for the root. In these strips 5 are formed grooves orchannels 6, some inclined in one direction and the others in theopposite direction,and to the Wooden roof-sheathing thus provided Iapply awaterproof cement 7, which may be of any desired composition, solong as it is plastic and can be spread over the roof-sheathing by meansof a trowel or other suitable implement to form a smooth and imperviouscoating of any desired thickness. Portions of the plastic mass enter thegrooves or slots in the strips 5, and thus serve to firmly key or securethe cement coating to the roof-sheathing.

If desired, a coating of fireproof paint or plaster may beapplied to thecomposition 7, so as to render the roof both fire and water proof.

The beams 8, which carry the floor of one story and the ceiling of thestory below, are not seated upon the walls, as usual, but are supportedupon the partition structures 2 of the building, and the latter are inturn hung upon beams or girders formed by securing to one or both sidesof each partition structure bars, strips, or beams of metal which restat the ends upon suitable seats formed on or in the side walls.

As shown in the drawings, the partitions consist of corrugated sheetmetal of any desired degree of thickness and having the corrugationsextending vertically, and in the structure shown in Figs. 1, 2, and 4:each of the supportingbeams or girders consists of a pair of angle-irons9, a pair of bars or straps 10, a pair of arched longitudinal bars orstraps "11, and a number of vertical bars 12, one of each of theelements 9, 10, and 11 being dis: posed on each side of the partitionand secured thereto by means of transverse bolts, rivets, or otherappropriate fastenings, a series of the vertical bars 12 being alsoemployed on each side of the partition. By this means an extremely stiffand rigid girder is produced with the employment of a minimum amount ofmaterial and possessing a minimum amount of weight, so that it servesnot only to support the partition hung therefrom, but also the floor andceiling structure hung upon the partition, the latter, owing to thecorrugations of the metal, being very rigid against vertical strain, andhence am ply qu alified to perform its intended duty.

In plastering the partition structures a thin adherent coating 21 isfirst applied to the corrugated sheet metal, and the main body 20 of theplastering is then applied to this first coating.

The floor-beams 8 are supported upon angleirons 13, secured to the lowerportion of each partition, as shown in Fig. 5, and the flooringboards14: are secured to these beams in the usual manner. The ceilingstructure, how

ever, differs from an ordinary ceiling in several respects and consistsof furring strips or bars 15, secured to the under sides of the beams 8at suitable intervals, these furringstrips carrying sheet-metal laths16, each consisting of a plate of sheet metal extending from center tocenter of adjoining furringstrips and suitably nailed or otherwisesecured thereto, each of these metallic laths having inturned-edgeflanges so as to properly engage with and key the mass of ceilingplaster17 applied to the under faces of the laths. In the spaces between thelaths and to a depth preferably equal to the depth of the flanges ofsaid laths I place masses 18 of a waterproof plastic composition, sothat a waterproof filling for these spaces is provided and the ceilingis rendered impervious to water. Hence no injury to the plastering of aroom below can result from an accidental escape of water in a roomabove, thus overcoming a well-recognized defect of ordinary plasterceilings.

It should be understood that although I have shown in connection withthe verticallycorrugated partition structures supporting beams orgirders, each composed of a number of bars or strips on each side ofsaid partition structure, this will not be necessary in all cases, as insmall or light structures a single bar on each side of thepartition-such, for instance, as the an gle-bars 9-may suffice, or thesupporting bars or strips may be on one side of the partition onlyinstead of upon both sides, the latter construction, however, beingpreferred.

By relieving the partition structures of all compressive strain the samecan be made extremely light, and economy is thus secured, while at thesame time a partition which is impervious to fire or water is obtained.Hence the structure is much preferable to ordinary lath-and-plasterpartitions, or even to those partitions which in modern fireproofstructures are composed of plaster applied to wirenetting or perforatedsheet metal, since these structures on the falling away of the plasterpresent no material obstacle to the sweep of flame, whereas a continuouspartition, such as that which I propose, offers an effective bar to suchprogress.

The beams or girders of the partition structure may, if desired, be madestrong and rigid enough to carry a brick partition or other wall, asshown, for instance, at 22 in Fig. 8, and continuous floor and ceilingstructures may be made by the use of corrugated sheet-metal strips, asshown at 23 in said figure, beams being secured in the corrugations ofthe strips, as at 24:, Fig. 9, for the attachment of the floorboards orceiling.

The ceiling maybe composed simply of forming-strips, as at 25, or it maybe a lathand-plaster ceilingsuch, for instance, as shown at 26the lathsbeing secured to the beams 24, and the partition may be covered in thesame waytha-t is to say, with forming-strips, as at 27, or lath andplaster, as at 28.

Having thus described my invention, I claim and desire to secure byLetters Pat ent 1. A building having an internal wall or partitionsuspended from a transverse beam or girder, substantially as specified.

2. A building having an internal wall or partition composed ofvertically-corrugated sheet metal, said partition being suspended from atransverse beam or girder, substantially as specified.

3. A building having an internal wall or partition suspended from atransverse beam or girder, and having a floor structure hung upon it,substantially as specified.

4. A building having an internal wall or partition consisting ofvertically-corrugated sheet metal, and bars or strips extendingtransversely of said corrugations, and secured to said sheet-metalstructure, so as to form a beam or girder from which the partition issuspended, substantially as specified.

5. A building having an internal wall or partition consisting ofvertically-corrugated sheet metal, said partition having secured to itsopposite sides metal strips or bars extending transversely of thecorrugations'and forming a beam or girder from which the partition issuspended, substantially as specified.

6. A building having a ceiling structure composed of metallic laths withinturned flanges for retaining the plaster, the spaces between saidlaths being filled with plastic masses of waterproof composition,substantially as specified.

7. A building having a ceiling structure composed of spacedfurring-strips secured to the under side of the floor-beams, andmetallic lathing-strips binding the spaces between said furring-stripsand secured to the latter, the spaces between said metallic laths beingfilled with waterproof plastic composition, substantially as specified.

8. A building having a continuous partition composed ofvertically-corrugated sheet metal, and a floor structure hung upon saidpartition and likewise composed of corrugated sheet metal, substantiallyas specified.

In testimony whereof have signed my name to this specification in thepresence of two subscribing witnesses.
